What is the principle of design that where used in the painting last supper?

The principle of design prominently used in Leonardo da vinci's "The Last Supper" is balance, particularly through the use of symmetry and focal points. The composition is organized around Christ, who is centrally positioned, drawing the viewer’s eye. Additionally, the use of perspective creates depth, leading the viewer's gaze toward the vanishing point behind Christ, further enhancing the sense of harmony and stability in the scene. This balanced arrangement effectively conveys the narrative and emotional intensity of the moment.
